     BALTIMORE, MARYLAND — An old postcard changed the lives of an eleven-year-old boy and

a very sick woman. The postcard had a picture of the steamship Titanic. The Titanic was the largest

ocean ship in the world. It hit an iceberg (冰山) and sank on April 14,1912. More than 1,500 of the

2,200 people on the ship were killed.

     The postcard was passed from one person to another for more than 80 years: Then it appeared at

a card show for people who liked to collect post cards. An eleven-year-old boy, Joey Russell, came to

the show with his grandfather. His grandfather knew everything about the Titanic and its trip from

England to New York. " Let' s buy that postcard ," he told Joey.  " It will be important someday."

     Two years later, Joey's grandfather took him on a special trip. They went on a trip to the North

Atlantic Ocean to watch as workers pulled the Titanic up from the bottom(底)of the ocean. Joey put his

special postcard in his bag for the trip. On the ship, Joey met Edith Haisman. This woman was on the

Titanic when it sank. She was one of the people who were rescued. Joey pulled the postcard out of his

pocket.  " Please sign this , Mrs. Haisman ." he said. She was happy to write her name on the back of

the postcard.

     When Joey got home, he put the postcard away and forgot about it. Then Kate Shelley, one of

Joey 's friends , told him that her mother was very sick. She needed an operation , but there was a

problem. The operation was very expensive, and the family needed $80,000 to pay for it. Friends and

relatives tried to help. But where could they get so much money?

     Then when Joey went to see the new movie " Titanic" , he had an idea. " Millions of people are

seeing this movie and reading about the Titanic ," Joey thought. He remembered the old postcard with

Edith Haisman 's signature on it.  "Maybe I can sell it for some money. Then I can help Kate 's mom."

     Joey told his mother and father about his idea to help Mrs. Shelley. His parents helped him try to sell

the postcard to the person who would pay the most money for it. Joey's story was on television and in

news papers. Joey and Kate even went to New York to be on a national TV show. After the show,

many people called in to offer money for the Titanic card. Someone bought it for $60,000.
